Rotation speed measurement at turbine
â–¶ How to fix
Check mounting position of the sensor (tolerance position, interspace). Check sensor. Change sensor.
What you'll see
No driver-visible symptom recorded.
System reaction
No or limited retarder function.
Diagnostic depth
Detection
Poor signal quality. The measured pulse duration/period durations vary more than allowed (no continuous signal available).
Possible cause
Torsional vibrations. Mounting position of the sensor not correct (tolerance position, pitch). Defective wheel of the pulse generator. Sensor defective.
